MATURATION • Initial batches in the range of 8 – 12% maturation • Subsequent batches with larger smolt sizes in the range of 30 – 40% maturation MITIGATION STRATEGY ON MATURATION • Revised temperature regime in the freshwater lifecycle stages • Revised photoperiod in the freshwater lifecycle stages • Revised photoperiod in the saltwater on-growing system
OBSERVATIONS • Significantly reduced rates of Precocious Parr in the Hatchery • Month to month increase in grilse %age in saltwater on-growing tanks has ceased • Some reversing of the maturation process when performing sample weights
• Note - Long term mitigation strategy involves the use of all female eggs

SUMMARY • The Sustainable Blue filtration technology has given very consistent performance,
even at extremely high stocking densities.
• Growth and maturation metrics have been observed at levels which support the Sustainable Blue business model.
• Husbandry issues associated with construction delays have caused growth and maturation issues.
